Oxygen Regulator and E-4 Certification
When buying a high pressure oxygen regulator for your live
well oxygen system, always confirm with the seller that the regulator you're
buying has passed the Compressed Gas Association (CGA) E-4 Ignition Test and is
certified and that it is not a repackaged medical oxygen regulator.
The Oxygen Edgeä regulators are
tested and E-4 Certified to be safe from ignition or fire caused by adiabatic
compression and other extreme operational conditions. Oxygen regulators sold
without E-4 Ignition Test Certification either fail to pass the test or those
regulators are not tested at all. Buying and using an oxygen regulator that is
not certified results in not knowing if your regulator will prevent compression
fires as well as regulators that are E-4 compression test certified
Safety on fishing boats is a matter of your peace of mind
when oxygen regulators are exposed to extreme saltwater environments. Many
brands of oxygen regulators sold to fishermen for livewell oxygen systems have
not passed the E-4 Ignition Test and are not certified. Caution is advised if
the regulator is not E-4 Ignition Test Certified. The Compressed Gas Association
(CGA) recommends E-4 Ignition Testing for all manufacturers making high-pressure
oxygen regulators. Be informed and always confirm with the seller about E-4
Testing and Certification before you purchase any oxygen regulator. The E-4
testing and certification is done only at the manufacturer's level prior to
wholesale distribution and branding by companies, distributors and retail
stores.
"Rules of the Oxygen Road"
- Gas and Cylinder SAFETY
If you DON'T KNOW the rules, it's worth taking a moment and
contacting an expert. This isn't air we're dealing with, it's pure oxygen.
Here's a few "rules of the oxygen road" regarding the Gas
and the Gas Cylinder:
Never look into your live well with a burning cigarette in
your mouth.
Always secure high-pressure gas cylinders (Oxygen, SCUBA, Helium
tanks) in your boat well with strong secure straps or brackets
during all transports. Never leave any high-pressure gas
cylinder upright or free standing at any time.
Never secure the oxygen tank in the boats bilge or battery
box, anywhere that oil or gasoline can contaminate the equipment.
Steel oxygen tanks require hydrostatic testing every 10
years, aluminum tanks every 5 years. The last hydrostatic test date is stamped
into the tank's shoulder.
Always use a clean rag with freshwater to clean oxygen system
components. If you need more than water for cleaning, ethanol is oil free... use
external on system components only, do not use ethanol internally anywhere
within the gas circuit. Use equipment only after all ethanol has completely
evaporated. Never expose ethanol vapors or ethanol to oxygen (the gas). Methanol
should never be use to clean oxygen equipment, methanol is not oil free.
Always crack (open the oxygen tank valve slowly to blow out
dust and foreign material) in the oxygen cylinder valve before connecting the regulator. After
connecting the regulator, open the tank valve slowly.
Always use system components that have been degreased, cleaned
and specifically certified for pure oxygen service, includes all oxygen supply tubing and fittings.
Never use cleaning solvents, WD-40, isopropyl alcohol
(household rubbing alcohol) or any other cleaning products with an
oil base.
Never use oil or oil based lubricants on any regulator
threads or tank valve threads. If you must use lubricants, use lubricants that are compatible with pure
oxygen service.
FIRE SAFETY USING OXYGEN the gas: A fire
extinguisher will not extinguish an oxygen enriched [24% O2 or greater] fire. Turn
off the oxygen
gas source terminating the gas flow or gas production and then put out the fire.
If a livewell oxygen system does not deliver enough oxygen for enrichment [< 24%
oxygen] the fire hazard is no greater than fire fueled with air.
Livewell oxygen systems that cannot deliver enough oxygen to
produce oxygen enrichment, provide >24% O2, are no more effective than an
aerator pumping air or livewell water pump pumping water through livewells and
bait tanks to keep fish and bait alive. Actually, they can kill bait or fish in
bait tanks and livewells quicker than aerators and water pumps.
If an oxygen generator salesman does not stress oxygen gas
(fire) safety, the oxygen generator gas production and delivery will not
deliver enough oxygen to be a fire issue.
If an oxygen generator fails to produce or deliver enough
oxygen, it's no better than any mechanical aerator or livewell water pump and
you already have had expensive negative experiences with air and aeration
equipment in the summer trying to keep bait and tournament fish alive and
healthy.
Fires fueled with pure oxygen [gas] are very different than
fires fueled with air [gas]. It makes no difference if the oxygen fueling the fire
comes from a PSA oxygen generator, electrolysis oxygen generator, liquid or compressed
oxygen system. The oxygen source must be terminated before the fire can be
extinguished if the oxygen generator is capably of oxygen enrichment (>24%
oxygen).
Knowing and understanding the gas, oxygen, and oxygen
equipment on your boat is necessary in order to be safe. Not knowing and not understanding the gas or your your equipment
increases risk on your boat not only for your safety, but everyone's safety.
Practicing the "Rules of the Oxygen Road" is necessary to maximize
safety.
Think safety and be safe when using this gas. This is not air!
